A cargo ship owned by South Korean shipping firm Hyundai Merchant Marine Co. rescued all 23 crew members of the Norwegian tanker Front Altair, which was on fire in the Gulf of Oman, the Korean company said Thursday.

The Hyundai Merchant cargo ship, the Hyundai Dubai, received a distress call from the Norwegian tanker around 6:40 a.m. earlier in the day (local time) and approached the Front Altair.

All crew members of the Front Altair safely abandoned the tanker and were picked up by the 30,000-ton Hyundai Dubai with rescue boats, Hyundai Merchant said.
